A method of manufacturing a barrier includes providing a frame; attaching a plurality of elongated members to the frame; disposing the frame within the housing such that the frame defines separate compartments within the housing; disposing at least one fan in a compartment separated by the barrier from another compartment; and disposing at least one electronic component in the another compartment.Type: ApplicationFiled: June 27, 2008Publication date: December 31, 2009Applicant: SUN MICROSYSTEMS, INC.Inventors: Brett C. Ong, Timothy W. Olesiewicz, Christopher H. Frank

Patent number: 7624544Abstract: The invention relates to a tool for preventing the vortex effect, comprising three corrugated tubes which extend helically from the upper end (2) of the tower (3), such as to cover only the upper part thereof. The helix pitch defined by the corrugated tube (1) along the length of the tower (3) is fixed using cords (5) which are attached at each revolution of the tube. The corrugated tube (1) is lifted with a cathead (6) which is disposed on the structure that is used to anchor (4) the tool to the tower (3), the structure comprising three T-shaped sections which form an X having sectors (9) fixed to the ends thereof. In addition, four legs (14) are welded to the aforementioned sectors and the tubes are wound around said legs.Type: GrantFiled: March 28, 2006Date of Patent: December 1, 2009Assignee: Gamesa Innovation & Technology, S.L.Inventor: Jose Ignacio Llorente Gonzalez

Publication number: 20090145053Abstract: An aerodynamic system attached to the outer side of the roof perimeter edge to mitigate wind generated vortices and uplift loads on the roof perimeter area of a building, applicable for both new constructions and retrofits of existing buildings. A roof edge guard is generally installed alongside a roof edge, and mounted onto an existing fascia or bargeboard. As an option most appropriate for new constructions, it can also be mounted directly onto a roof frame member in place of fascias or bargeboard. The configuration modifies the cross-sectional shape of otherwise abrupt roof edges that tend to generate strong vortex during high winds.Type: ApplicationFiled: February 6, 2009Publication date: June 11, 2009Inventor: Jason JianXiong Lin

Publication number: 20090100791Abstract: A method of making a shim comprises the steps of providing a first structural component, such as a rib foot of an aircraft wing. The rib foot is then scanned or mapped to generate the surface profile of the rib foot. The shim is then formed to include a feature on its surface which complements the surface profile of the assembly surface.Type: ApplicationFiled: September 16, 2008Publication date: April 23, 2009Applicant: AIRBUS UK LIMITEDInventors: Amir KAYANI, Ian L.

Patent number: 6606828Abstract: A roof edge fascia or coping cover having an aerodynamic exterior shape mainly comprising a lower face portion, an intermediate face portion, and a top face portion. The lower face portion is either generally vertical, or sloping or curving upwardly and outwardly, forming an angle within 60° to the vertical outer wall surface of a building. The top face portion, of a substantial lateral size, is generally disposed within ±25° from horizontal. The intermediate face portion, having at least one segment of a substantial lateral size sloping or curving upwardly and inwardly, connects the lower and top face portions. Slope changes at a junction between any two adjacent face portions, or adjacent segments thereof, are generally less than or equal to 50°.Type: GrantFiled: December 6, 2001Date of Patent: August 19, 2003Inventors: Jason Jianxiong Lin, Liddy Miaoli Chen
